Adrian Shephard likes to think of himself as a pretty adaptable man. Throw him into a strange situation in a new environment and he takes to it quickly, under just about any circumstances you could care to name. Mama Shephard saw to it that all her kids grew up like that. It's served her middle child well in all kinds of places and situations, whether it involved a flood almost wiping out his hometown when he was a boy, or being thrown into basic training straight out of high school, or waking up in the belly of an underground research facility after a plane crash. Shoot, even going from escaping that facility to the middle of nowhere twenty years after the fact wasn't all that hard to adapt to, with his upbringing and training.
But there are some things he's just not prepared for, and while he tries to deal with those as best he can, the usual coping mechanisms don't always work so well. He's had to suppress his dislike of flying before. Getting shot out of the sky over Black Mesa turned that dislike into a fear, which he could cope with, but now-
Well, now he's got to use a helicopter, which is pretty much the flying machine that most wants to kill its passengers as far as he knows. And even better, he's got to pilot the damned thing, because of his two current companions
one is too incapacitated by head injury and drugs to even sit up straight and
the other one's never so much as been behind the wheel of a car.
They didn't exactly cover this in Basic. You'll excuse Shephard for singing quietly under his breath to try and keep himself on an even keel. It's a long way to wherever it is they're going and he can only read about a third of the navigational instruments in front of him.
"...clear blue skies over Germany
Came a roar and a thunder men had never heard
Like the screamin' sound of a big war bird.
Up in the sky, a man in a plane
Baron Von Ricthofen was his name..."
